Heat sink clip and assembly

1. A heat sink clip comprising: a body having a securing portion formed at one end thereof; an actuating member being pivotably mounted to the securing portion of said body and having a main body, the main body defining an open aperture therein; and a movable fastener being pivotably connected to the open aperture of the actuating member; said actuating member being turnable relative to said body between an unlocked position and a locked position for locking a heat sink to a retention module and unlocking the heat sink from the retention module; wherein an upper portion of said movable fastener defines an opening therein, one portion of the movable fastener above the opening being received in the open aperture of said actuating member, whereby the movable fastener is pivotably connected to the actuating member, and a lower portion of said actuating member extends through the opening.

2. The heat sink clip as described in claim 1 , wherein said body has a locking arm integrally formed at the other end thereof, and the locking arm defines a mounting hole therein for engaging with the retention module.

3. The heat sink clip as described in claim 2 , wherein said body defines an elongated slot between one end and the other end.

4. The heat sink clip as described in claim 1 , wherein a bearing portion is formed at the one end of said body, and said actuating member rests on the bearing portion of said body in the locked position.

5. The heat sink clip as described in claim 1 , wherein the securing portion of said body defines a pair of coaxial pivot holes therein, the main body of said actuating member defines a pair of coaxial pivot holes below the open aperture, and the main body of the actuating member is pivotably mounted to the securing portion via a pivot extending through the pivot holes of the actuating member and the securing portion.

6. The heat sink clip as described in claim 5 , wherein the actuating member comprises an operating handle extending from an upper portion of the main body.

7. The heat sink clip as described in claim 5 , wherein a lower portion of the movable fastener defines a mounting hole therein.

8. A heat sink assembly comprising: a retention module; a heat sink placed on the retention module; and a heat sink clip, said heat sink clip comprising: a body placed on the heat sink, said body having a securing portion formed at one end thereof, the other end of said body being attached to the retention module; an actuating member being pivotably mounted to the securing portion of said body at a connecting point; and a movable fastener having an upper portion and a lower portion, the upper portion of said movable fastener defining an opening therethrough, the upper portion being attached to said actuating member, the lower portion being sleeved onto the retention module; said actuating member being turnable relative to said body between an unlocked position and a locked position, wherein, in the unlocked position, the connecting point formed between the securing portion of said body and the actuating member is located at one side of the movable fastener, and wherein when the actuating member is turned from the unlocked position to the locked position, the connecting point traverses through the opening of the movable fastener to be located at an opposite side of the movable fastener.

9. The heat sink assembly as described in claim 8 , wherein said actuating member defines an open aperture therein, the opening of said movable fastener is sleeved onto said actuating member at the open aperture.

10. The heat sink assembly as described in claim 8 , wherein said body forms a bearing portion close to the securing portion thereof, and in the locked position, said actuating member rests on the bearing portion.

11. The heat sink assembly as described in claim 8 , wherein the heat sink defines two parallel grooves therein, said body defines an elongated slot between the one end and the other end thereof, said body being received in the grooves of the heat sink with fins of the heat sink extending through the elongated slot.

12. The heat sink assembly as described in claim 8 , wherein said actuating member is located on an outside of the heat sink.

13. A heat sink clip comprising: a body having a first end forming a locking arm with a mounting hole adapted for engaging with a locking block of a retention module and a second end opposite the first end; an actuating member pivotably mounted on the second end of said body and defining an open aperture at an upper portion; and a movable fastener having an upper end defining an opening for sleeving onto the upper portion of the actuating member at the open aperture thereof and a lower end defining a mounting hole adapted for engaging with a locking block of the retention module; wherein said actuating member is movable between a locked position and an unlocked position, and said actuating member rests on the second end of said body in the locked position.

14. The heat sink clip as described in claim 13 , wherein the second end of said body forms a bearing portion, the upper portion of said actuating member rests on the bearing portion of said body in the locked position.

15. The heat sink clip as described in claim 13 , wherein one portion of the movable fastener above the opening being received in the open aperture of said actuating member, whereby the movable fastener is pivotably connected to the actuating member, and a lower portion of said actuating member extends through the opening.
